...this is try to be a fair question, so please understand that point; kind of curiosity.
I wanna hear other voices regarding this.

So, I just watched couple of runs (in USA) videos and noticed that almost all the bikes (except a few HD shovels) are somewhat "new".
Almost all are HD and some Japs; in other there are some new Triumphs..

the question is: where s the Triumphs? where s the other HD s?
I mean, here we have a forum with tons of these motorcycles...but seems that no body on the main runs (USA)?

Yes, I know about very long runs and problems with very old machines or smaller cc ones, but what happened with the Bonnies? A T120 can do the run, better yet a T140 or Trident...and the shovels and panheads? that sport a very big engine that can handle long runs without hurting the engine.

-Those runs are not super bikes runs so the speed is kind of normal road or freeway speed.

-All that time we put on these bikes for what actually?
kind of thinking in loud voice

I'm just generalizing here, but I think allot of people think of Triumphs as around town bikes. I know that here in AZ, our freeway speeds are all marked at 75, but if your running under 80 or so your going to get run over. Just my .02

when I first bought my triumph thruxton in 2004 I rode with the rat pack a couple of times. I thought it was ok but none of those guys shared my passion for old bikes. I stopped riding with them and have since sold my Thruxton. I like riding alone or with 1-2 other people. Not a lot of old bike riders around here. Big charity rides and "bike night" crowds that would rather drink and ride home than tune and ride an old bike aren't my thing. Perhaps you need to watch different vids? One world studios puts out some good stuff with older bikes and cars in it.

You're judging popular culture via viedo, never a good idea. In the US, for every vintage Triumph or Harley, there are 25 brand new Couch Glides (or Japanese copies thereof) ridden by accountant "bikers" who like to play dressup. Those are the people that overwhelmingly dominate the big events because they're the people that spend shitloads of money.

...today just watched EDR and Revenge runs
last week I watched couple of smaller runs like Born free

Oh, well forget what I said then, I assumed you meant more mainstream events. There have been old bikes at everything you mention, I know that for a fact, but some guys will pull out the newer iron to avoid potential problems.

And yeah, what the guy said above, EVOs and twin cams aren't "new" anymore...unless you're riding a new one.

Speaking from experience, I was on the Revenge Run II Last year (on my '73 Yamaha), and was surprised at the lack of old bikes (not one old Triumph). There were definitely some but not the amount that I've experienced on the Gypsy Run the last few years. That run has a majority of old bikes I think. Although doing 80 on the highway for an hour last year didn't help the vintage bikes! This year I'll be on a Triumph or Shovel- I would have been on the Triumph last year but couldn't get it done in time. The Brooklyn Invitational has had a good vintage turnout also. I guess it just depends on what run you see.

I've had issues myself as president of a vintage bike club trying to get people to leave the new ones home on scheduled rides and use the oldies...I guess I must have made enough noise as most of the core group now show up on what we term as vintage bikes. I think it boiled down to laziness, it was just easier and more comfortable to hop on a new bike and push the little button than it was to use the old machines. We mostly ride the side roads, so we don't go far, but we do run 6-10 hour days...and get sore arses.

don't know about the us but all my friends ride the oldies
most pre evo hd's and a couple triumphs and indians
also a couple are running aroynd on pre '85 xs650's or beemers
